5 is a plan view of the insulating body 210, FIG. 6 is a perspective view of the guide member 250 according to an embodiment of the present invention viewed from the first direction, and FIG. 7 is a guide member according to an embodiment of the present invention. (250) is a perspective view viewed from the second direction. Also, FIG. 8 is a perspective view of the guide member 250 according to an embodiment of the present invention as viewed from the third direction.

6 to 8 , the guide member 250 includes an upper surface 610 , a first inner surface 632 , a second inner surface 634 , and a third inner surface 636 .

The first inner surface 632 , the second inner surface 634 , and the third inner surface 636 extend from the upper surface 610 and are curved inward (ie, in the groove 270 direction) of the insulating body 210 . is the side The first inner surface 632 and the second inner surface 634 are surfaces formed for contacting or close to the longitudinal inner surface 211 of the insulating body 210 , and the third inner surface 636 is the insulating body 210 .

Specifically, the curved portion 620 is a longitudinal inner surface 211 of the insulating body 210 from the end portion 633 of the first inner surface 632 curved to the longitudinal inner surface 211 of the insulating body 210 . ) may be continuously formed up to the end portion 635 of the curved second inner surface 634 . This type of curved portion 620 is effective in preventing damage to the receptacle connector 200 . For example, if a portion of the curved portion 620 is cut off, when pressure is applied to the receptacle connector 200 for engagement with the plug connector 100 , the shape of the guide member 250 may be deformed, and thus Accordingly, breakage of the insulating body 210 and separation of the contacts 230 may occur. Such a damage problem is more serious in the case of connectors used in miniaturized devices such as smart devices. In other words, as devices become smaller, connectors must also be miniaturized. When pressure is applied to a small connector, breakage is more likely to occur than a relatively large connector.

The curved portion 620 has a center of curvature of a curved shape formed along the first inner surface 632 to the third inner surface 636 from the upper surface 610 to the outside (ie, the first inner surface 632 to the first inner surface 632). 3 As the rear side of the inner surface 636, for example, it may be formed to be located in the space between each inner surface and each outer surface), and any form for coupling with the plug connector 100 may be applicable. have.

The cut-out shape of the corners 638 and 639 may be a hemispherical shape, but depending on the embodiment, the lower ends of the corners 638 and 639 may not be cut.

A deep drawing process may be performed to continuously form the curved portion 620 between the upper surface 610 and the first inner surface 632 to the third inner surface 636 . The deep drawing process is a process of manufacturing a seamless container-shaped product using a plate material. Specifically, the product is manufactured by compressing the plate material in the circumferential direction and pressing it in the depth direction. That is, in one embodiment of the present invention, a deep loading process is applied to the plate material for manufacturing the guide member 250 , the upper surface 610 , and the first inner surface 632 having a continuous curved portion 620 to A third inner surface 636 may be manufactured.

In addition, the guide member 250 includes a first outer surface 642 , a second outer surface 644 , and a third outer surface 646 extending from the upper surface 610 and bent to the outside of the insulating body 210 . do. The first outer surface 642 and the second outer surface 644 are surfaces formed for contacting or close to the longitudinal outer surface 215 of the insulating body 210 , and the third outer surface 646 is the insulating body 210 . A surface formed for contact with or proximity to the width direction outer surface 217 of the 210 .

As can be seen in FIG. 8 , a soldering part 648 for substrate mounting is formed at the lower end of at least some of the first outer surface 642 , the second outer surface 644 , and the third outer surface 646 . can 8 shows that two soldering portions 648 are formed on each of the first outer surface 642, the second outer surface 644, and the third outer surface 646, which is only an example. , the soldering portion 648 may be formed only on some of the outer surfaces of the first outer surface 642 , the second outer surface 644 and the third outer surface 646 , and the number may be variously changed. . The receptacle connector 200 is mounted on the board by soldering the soldering part 648 formed on the lower end of at least a part of the first outer surface 642 , the second outer surface 644 and the third outer surface 646 to the board. can do it

According to an embodiment, the guide member 250 according to an embodiment of the present invention extends from the first outer surface 642 and the second outer surface 644 to the electrical terminal (eg, the plug connector 100 ) , a contact portion 152 included in the guide member 150 of the plug connector 100 (see FIG. 2 ) or a contact portion 650 in contact with the contact 130 of the plug connector 100 ) may be further included. The contact portion 650 may include a left contact portion 650a extending from the first outer surface 642 and a right contact portion 650b formed extending from the second outer surface 644, and the left contact portion 650a and The right contact portion 650b may have the same shape.

The contact portion 650 may function as an additional contact point other than the contacts 230 for electrical coupling with the plug connector 100 , and the contact portion 650 may increase contact reliability with the plug connector 100 . Recently, a connector that can operate stably even at a high current is required, and when a high current signal is transmitted only with the general contacts 230, problems such as heat generation may occur. A contact portion 650 may be provided.

The contact portion 650 may form a four-point contact with the plug connector 100, specifically, a two-point contact is formed at the left contact portion 650a extending from the first outer surface 642, and the second outer surface ( A two-point contact point may be formed in the right contact portion 650b extending from 644 .

In addition, the structure of the contact portion 650 is different from that of the general contact 230 . Specifically, referring to FIG. 3 , in the case of the general contact 230 , the first end 231 is in contact with the substrate, and the second At the second end 232 and the middle region 233 make contact with the contact 130 of the plug connector 100 . When the shape of the contact part 650 is to be implemented as that of a general contact 230 , there is a problem in that it is difficult to secure a plate material for forming the guide member 250 .

9 and 10 show a flatly spread out the contact part 650 implemented in the shape of a general contact 230, and as shown in FIGS. 9 and 10, a contact 230 of a general form is When unfolded flat, as the two regions 810 and 820 serving as the contact portions 650 of the plate material extend long, the two regions 810 and 820 may overlap each other. In other words, the plate material for forming the guide member 250 should have a shape of a flat spread of the guide member 250, but the regions 810 and 820 that become the contact portions 650 among the plate materials face each other. Since it extends long enough to overlap or collide, it is difficult to secure a plate material of such a shape.

In addition, as shown in FIG. 11 , a general contact 230 is manufactured as a contact 230 according to a bending process in a state in which the ends of several conductive pins 1010 are attached to the carrier 1020 , a guide member ( Among the plates for 250 , it is difficult to apply such a manufacturing process to the guide member 250 in that the regions 810 and 820 , which are the contact portions 650 , must be bent while facing each other.

Accordingly, according to an embodiment of the present invention, the contact portion 650 has a shape different from that of the general contact 230 . 6 to 8 , the contact portion 650 extends from the first outer surface 642 and the second outer surface 644 and is bent upwardly. A first terminal 656 and a first outer surface 642 are formed. and a second terminal 657 extending from the second outer surface 644 and bent downward. The first terminal 656 and the second terminal 657 may be connected through the first outer surface 642 and the first connecting portion 662 , and the second outer surface 644 and the second connecting portion 664 . . Specifically, the first terminal 656 is formed by bending while being connected to the upper portions of the first and second connectors 662 and 664 , and the second terminal 657 is formed between the first and second connectors 662 and 664 . It may be formed by bending while connected to the lower portion of the connection part 664 .

The first terminal 656 includes an upper region 651 bent in the horizontal direction and an end region 652 bent in the lower direction, and the second terminal 657 includes a lower region 653 bent in the horizontal direction and It may consist of an end region 654 bent in an upward direction. The upper region 651 and the end region 652 of the first terminal 656 may have a substantially right angle shape, and the lower region 653 and the end region 654 of the second terminal 657 are also substantially perpendicular. may have a shape.

The end region 654 of the second terminal 657 may be located more inward than the end region 652 of the first terminal 656 . That is, the bent point B1 for the formation of the end region 654 in the lower region 653 of the second terminal 657 is the end region 652 in the upper region 651 of the first terminal 656 . It may be located further away from the outer surfaces 642 and 644 than the bent point B2 for forming.

An end region 652 of the first terminal 656 and an end region 654 of the second terminal 657 may be electrically connected (ie, contacted) with the electrical terminal of the plug connector 100 . A bent portion 658 bent to improve contact force with the plug connector 100 may be positioned at some points of the end region 654 of the second terminal 657 , and the bent portion 658 and a groove to be described later It can be connected as a two-point contact structure with the plug connector 100 through 655 .

Unlike the general contact 230, since the end region 652 of the first terminal 656 and the end region 654 of the second terminal 657 make electrical contact, even when the contact portion 650 is flattened, the guide member ( 250) among the plates for the left contact portion 650a and the region corresponding to the right contact portion 650b, there is no possibility of colliding or overlapping with each other.

Also, as illustrated, a groove 655 may be formed in at least one of the end region 652 of the first terminal 656 and the end region 654 of the second terminal 657 , and the groove 655 may be formed. ) may be combined with a protrusion formed on the electrical terminal of the plug connector 100 (eg, a protrusion 155 formed on the guide member 150 of the plug connector 100 (refer to FIG. 2 )) to enable stable coupling. The groove 655 may preferably have a rectangular shape, but any shape corresponding to the protrusion may be deformed.

Depending on the embodiment, instead of the groove 655 , a protrusion may be formed in at least one of the end region 652 of the first terminal 656 and the end region 654 of the second terminal 657 . In this case, the plug A corresponding groove may be formed in the electrical terminal of the connector 100 .

The receptacle connector 200 according to an embodiment of the present invention can achieve high strength through the guide member 650 , and thus the possibility of breakage due to excessive pressure is reduced. In addition, since the curved portion 620 guides the correct seating of the plug connector 100 , it can be easily combined with the plug connector 100 .
